Specification forming part of Letters Patent No. 201,643, dated March26, 1878; application filed October 8, 1877..- v

. Be it known that I, JAMES" S. BOG-LE, of Springfield, county ofClarke, State of Ohio, have invented anew anduseful Improvement inGrain-Drills, of which the following is a full, clear, and exactdescriptiomreference being had tothe accompanying drawings, making partof this specification, in which Figure 1 is ,a perspective view of aportion of the grain-box of a seeding-machine, showing the relation ofthe distributers thereto;

Fig. 2 is a perspective view (enlarged) of one of the distributersdetached. Fig. 3 is a side elevation of the same. Fig. tis a sideelevation of the casing-plate, within and between which and thefeed-wheel the measuring-channel is formed, showing the relationof thefeedgage thereto; and Fig. 5 is aperspective view of feed-wheel and oneof its casing-plates;

Similar letters of reference denote corresponding parts wherever used.

The invention relates to the mannerof pivoting the gages within thecasings of the dis; tributing-wheels, and to. the m'eansemployed foreffecting the adjustment of said gages, and

will be best understood from the following description with reference tothe drawings, in whichn A represents a grain-boxer hopper, of any usualor preferred form or construction, and, to the bottom of which thedistributer-wheel casings are connected, through flanges on the upperopenv ends, in any usual manner.

B B represent the two parts of the divided casing tothedistributer-wheels O, the one, B, adjacent to the flanged side of thewheel having the secondary hopper and seed-channel formed in it, asshown in Figs. 2, 3, and 4. This hopper and channel, starting from thebottom of the grain-box above the distributerwheel shaft D, extendsthence, converging in form, in front of, around, under, and to the rearof said shaft, as shown in Fig. 4 at b N, the relation of the shaft orthe bearing in the casing therefor being indicated at c. The

inner Wall of said channel adjacent to the shaft consists of a flange, bwhich projects laterally from the casing-plate 13 within the flangedfeed-wheel G, resting in contact or in close proximity with the verticaldisk of said wheel, serving to close the side of the channel adjacent tothe distributer wheel shaft, as

shown. The lowerendof this flange is'supplemented by the. swinging endofan adjustable gage, E, which extends upward in rear of the(listributerrwheelshaft, and is pivoted within. the casing-plates at apoint, 6, above said shaft, asshown. The foot or swinging end of thisgage movesout and in in close proximity with ,and: protected by thelower end of flange bflwhich conforms in shape to the path ormovement-of the gage, the two extreme positions of which are shown inthe full and dotted lines, Fig, 4. i

By this arrangement of the gage it will be seen that the dischargeor-outlet end b of the feed-channel may be enlarged or contracted atwill by the adjustment of the gage for regulating the discharge of thegrain. The gages thus arranged within the casings. are adjusted by meansiof. arms'connecting. them with a rock-shaft, G, asfollows, viz:Therock-shaft extends along the rearv lower corner of the grain-box in aline parallel. with the distributer-wheel shaft, (see Fig. 1,) and ismounted in half-bearings at f in the casing-plates, being held in placethere- 'in by removable half bearing-blocks h, by the aid of which theshaft may be removedand replaced at will. This shaft G has secured to ita number of arms, g, provided with sleeves surrounding the shaft, andwith set-screws, by means of which said arm 9 may be adjusted on theshaft and held at any desired point of adjustment thereon.

The swinging ends of these arms are provided with longitudinal slots 9,with which points or spurs e on the sides of the gages,

and passing out through slots at b" in the casing-plates, engage,connecting the pivoted gages with the vibrating arms g.

These points or spurs e, by preference, are made tapering or conical inform, in such manner that, as the arms 9 are adjusted on thecasing-plates within the periphery of the distributing-wheels, and theirpivotal centers being placed above the distributing-wheel shaft, asexplained, the foot or gage part is removed as far as practicable fromthe pivotal center under such arrangement, thereby making its movementsless abrupt, and serving as nearly as practicable to preserve thedischargingoutlet of the channel from material change of form under thedifl'erent adjustments of the gage-a matter of considerable importancein maintaining a uniform action upon and in preventing the wedging andcrushing of the gram.

The pin or spur 0, instead of being formed on the gage, may be formed onor applied to the arm 9, and the slot may be formed in the gage at apoint intermediate between its pivot and its gaging end or foot, eitherarrangement serving to connect the adjustable gages arranged within thecasings directly with vibrating arms on a'single rock-shaft arrangedwithout the peripheryof the feed-wheels, thus sim- 'pli'fyin' g themechanism required for adjusting the gages, and at the same timeobviating all loss of motion between the parts, as explained.

In some cases it may be found sufficient to.

usestraight cylindrical spurs; butthe tapering 'or conical form ispreferred for the reasons stated. a l

The shaft G is provided at one end, or at any convenient point in itslen gth,'with a lever,

K, extending upward within reach of the driver, I and moving over agraduated rack and sectorplate, L, by means of'which the lever andthegages, through their connection with said lever, as described, may beheld at any desired point ofadjustment. suitable marks on said plateserving to indicate the position of the gages and the quantity sown peracre.

The manner of setting the gages uniformly is the same as that describedin a former application filed July 19, 187 7 consisting in providing thedistributer-wheels with annular ledges, upon which the gages are allowedto drop or rest, and the actuating-arms g are then adjusted uniformly onthe shaft, to conform to the described position of the gages, and toengagetherewith when being fastened to the shaft by their respectiveset-screws. IAny movement of the shaft will be imparted uniformly to thegages throughout its entire length.

The machine, except in the details particularly pointed out, may beconstructed and may have its parts arranged in any usual or preferredway, and need not therefore be further described. 7

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- I 1. In a grain-drill, a gage pivotedwithin and to the distributer-wheel casing, and operated by means of aslotted arm connecting it with a rock-shaft arranged without theperiphery of the feed-wheel. 2 A gage pivoted within .and to thecasingof the distributer-wheel at a point above the driving-shaft bearing, andoperated by means of ,a slotted arm and rock-shaft, substantially asdescribed.

3. The pivoted gage provided with a taper- .ing stud 0r pin, engagingwith a slotted actuating-arm for obviating loss of motion between saidparts, as described.

4. The combination of v a series of pivoted gages E and adjustableactuating-arms g, arranged and operating substantially as described.

5. The rock-shaft G, provided with theadjustable arms for actuating theseparatelypivoted gages,' mounted in open bearings in the casing-plates,in combination with theremovable hangers or half-boxes h, attached tothe seed-box, substantially as and for the purpose set forth. j 4 j p v,

In testimony whereof I have hereunto set my hand this 29th day ofSeptember, A. D. 1877.
